Importing a Terrain Heightmap

In order to support full, 32-bit heightmap resolution, use one of the following file formats when you import a heightmap file.

  • .asc

  • .bt (binary terrain) – Highest precision

  • .tif (32-bit)

The following file formats are supported but not recommended. These file formats are imported with less than 32-bit resolution, which can cause blocky-looking terrain.

  • .pgm (16-bit)

  • .raw (16-bit)

  • .r16 (16-bit)

  • .png (8-bit)

  • .bmp (8-bit)

  • .tif (8-bit or 16-bit)

If you attempt to import a file that was created with a different resolution than your existing heightmap, Lumberyard prompts you to do one of the following:

  • Clip your imported file to remove any values that are outside the boundary of your existing heightmap.

  • Resize your imported file to shrink or stretch to fit the heightmap. Resizing may introduce artifacts that can cause blocky-looking terrain.

To import a heightmap

  1. In Lumberyard Editor, choose Game, Terrain, Edit Terrain.

  2. In Terrain Editor, choose File, Import Heightmap.
